Most of our use of Alexa revolves around skills. But they are all around smart home products we have like Wemo, Harmony Hub, etc.
The bugbear I have (being a Canadian user) is the region lockouts. A lot of existing skills aren't ticked for English (Canada) support, so we're stuck waiting for skills to show up.
I contacted some product companies for some skills I was waiting for, and it didn't even seem like companies were notified of the region setting or the recent Canadian release.
